Answer:
First of all since they are dividing subtract the powers of the base from each other .
Make sure the bases are the same.
((6^7-6)(3^3-4))³
((6)(3^-1))³
(6³)(3^-3)
216 × 1/27
= 8
That's option d.
Hope this helps.
Negative exponents create the reciprocal of the original number:
2^2=4
2^-2=1/4
4^4=64
4^-4=1/64

<u>What number</u> <u>divided by</u> <u>-7</u> <u>is equal to</u> <u>-15</u>
∨ ∨ ∨ ∨ ∨
x ÷ -7 = -15
Multiply -7 to both sides:
COS A=0.8
Step-by-step explanation:
2^6+8^2
100
sqrt(100)=10
8/10
0.8
Answer:
Step-by-step explanation:
Let number of large pizzas be l and number of small be s.
<u>Then we have equations:</u>
- l + s = 100
- 16l + 11s = 1550
<u>From the first equation, we get l = 100 - s and substitute in the second equation:</u>
- 16(100 - s) + 11s = 1550
- 1600 - 16s + 11s = 1550
- 5s = 1600 - 1550
- 5s = 50
- s = 10
Number of small pizzas is 10
